(Inženjersko društvo za koroziju, Beograd, 2021)
Polomljene epruvete za ispitivanje niskocikličnim zamorom čelika Nionikral 70 (NN-70) osnovnog materijala (OM) i simulirane zone pod uticajem toplote (SZUT) poslužile su NAM za izradu uzoraka za ispitivanje otpornosti na ...
Kinetic of corrosion reactions in acid and neutral solutions on electrochemically deposited Ni-W alloys / Kinetika korozionih reakcija u kiselim i neutralnim rastvorima na elektrohemijski taloženim legurama Ni-W
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
Ni-W alloys were electrochemically deposited from an ammonia-citrate electrolyte on rotating disc electrode with a gold disc, by direct and pulsating current. The corrosion potential and kinetics of cathodic and anodic ...
Organoclay-polymer nanocomposites / Organoglina-polimerni nanokompoziti
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved ...
